Disclaimer: By making this question Rube' does not admit or implies that he might or might not pop the question, suggest it, think about it, or anything else.
So... in your own personal experience, when the question finally poped, did the potential spouse did it ring in hand, or did the ring appeared later?
If the ring appeared later... What was the reason for the ring's delivery delay?
PS: Bonus question... If the potential future spouse does not wear/use any rings, how you get the size correct without giving away the plans?
PS #2: Some important details... The person in question has never marry, this would be the first time.
